Patented Aug. 20, 1935 CHART HOtDEfR v I HoraceLI Iouse, Nubieber,Calif. v l, Athenians 19, 1934,fseia111vt. 731,298 Claims. (01'. -82)This invention relates to illuminated holders for time schedule chartsused'by locomotive engineers, and particularly represents refinementsand improvements over. the devices. shown in my On'e object of thepresent invention;- asabove indicated, is to refine, improve.andfgenerally simplify the construction of the holder. 'Another objectis to combine ina singleunit anillumi 1 nated holder for a schedule. orchart and a flash light :suitable for general utility purposes and suchas are now commonly carried by engine men; and so arranged that itaddsno expense to the construction of the holder other thanthat of thesmall reflector and additional light bulb. These objects Iaccomplish-by. means of such structure and relativdarrangement of .partsas will fully appear by a perusal of .the following specificationand'claims. 1 i

. ,:In the drawing similar charactersof reference indicate correspondingparts in .the several views:

. Figure. 1 is'a longitudinal elevationofamyim proved holder. g H Figure2 is a longitudinal section .ofthe. same partlybrok'en away. 1

Figure 3 is a cross sectionjon the line. .-3:3 of

Figure 2. J y 1 Figure 4 is a longitudinalsectionof the slidable lightunit taken on the line 4.-4 of'FigureZ.

Referring now more particularly to the characters of reference on thedrawing, the holder comprises a laminated cylindrical barrel which con-I sists ofinnerand outer metal, shells l and 2 'respectively separatedbya lamination oi? stiff insulated material 3. The barreliis provided witha longitudinal slot 4 extending fromione end toward but terminating.short of theoppo'site end. The outer shell 2 terminatesshortof theshell I onone end andthe spacing between its separated .edgesisgreaterlthan the width of;v the slot 14.

Also the lamination 3 extends beyond both metal sleeves at q the end ofthe, barrel opposite; said 9ne-end.,-

.-: :;The.;s'eparated. edges of the inner shell along 7 rails also serveas a support and guide for the sliding illuminating unit by means ofwhich the mileage strip supported by the guides can be read at night aswell as the matter on the chart adjacent the slot. This unit comprisesmetal elements .Tforming a substantial cylindrical housing and separatedfrom each other by an insulation core 8 disposed inside the housingandarrangedso that one end and the adjacent bottom portion. of the housingis left open. xAbulb Sis mounted in the core to face the open end of thehousing, one terminalof the bulb spaced relation thereto is a tubularopen ended spool ll adaptedto contain a number of dry cells' l2 disposedin contacting end to end alinement. The spool has enlarged flanges. l3between which the timetable schedule is disposed. Longitudinally alinedsmall rigid rods it are secured to and project toward each other. fromthe 1 flanges in parallel and close relationship/to the spool, beingadapted to project between the leaves ts PATEN S P- t .of the time tableatthe junction of said leaves 5 -2 and insulation 3, so that said capcontacts with the. shell .I.. The cap is knurled so that it can bereadily turned by hand while ofcourse .be-

ing removable from the barrel. Said cap. how

.ever is prevented from being too readily removed,

without restricting its freedom of rotation, by

suitable means such as a shallow circumferential fridge. It .on thebarrel and a cooperating'groove '11 about the bore of the cap. 'Ihelslotdextends through said end of the barrel as stated and the shells areresilient with a tendency. toexpand. ".In. this manner when theyarei.-compressed to allow the cap. to extend over the same they willthen engage the cap with a frictional grip when .the compressivepressure .is released and will hold the ridge and groove in cooperatingrelationship.

Removably mounted in the cap end of the spool. is a plug l8 having aspring l9 therein engaging the adjacent end of the adjacent dry cell sothat contact between said battery and the inner shell of the barrel ismade and maintained.

A ring 28 is rigidly secured to and projects from the plug, serving notonly as a means to turn the plug but also to hang the device up when notin terminal and the adjacent end of the adjacent battery I2 and engagesthe latter. This contact-- strip extends and is connected to the outershell I so that there is no direct connection between" the shells. Thecircuit to the. sliding lamp will closed.

The inner shell is connectedito the flash lamp reflector, in order tocomplete the circuit to the bulb 24 by means of a metal strip: 26mounted on the insulation lamination 3, which strip at one end engagesthe reflector and is adapted at its otherend to be selectivelyengaged-with the inner shell I by a sliding switch 2'! of the usualcharacter used on flash lights. It will therefore be seen that the flashlight while using thesame batteries as the chart illuminating light canbe,

energized separate therefrom and the energizing of either light will notaffect or interfere with the use of the other.

From the foregoing description it will be readily seen that I haveproduced'such a device as invention Having thus described .my invention'what 1 claim as new and useful and desire to secure by LettersPatent is:

1. A combination chart illuminator and flash light comprising a barrelto receive a rolled chart and having. a longitudinal 'slot through whichthe chart maybe withdrawn, an electric light mounted on the outside ofthe :barrel in position to illuminate the withdrawn portion of thechart, another electriclight mountedin the bar.- rel at oneend inoutwardly facing relation, abattery mounted in the barrel and. common toboth lights, and separate switchesfor the lights;

2. A chart holder including abarrel having a longitudinal slot open toone .endthereof, a: spool to support a chart disposed within thebarrel'in concentric relation thereto, and a cap for the barrel rigidwith the spool atone endthereof; said cap being turnably and removablymounted on the barrel at the. adjacent end.

the cap without interfering with its freedom of rotation.

4. A combination chart illuminator and flash light comprising a barrelto receive a rolled chart and having a longitudinal slot through whichthe chart may be withdrawn, an electric light mounted on the outside ofthe barrel in position to illuminate the withdrawn portion of the chart,another electric light mounted in the barrel at one end in outwardlyfacing relation, a battery mounted in the barrel, separate circuitsbetween said battery and the lights and including the barrel, andseparate switches in said circuits.

5. An illuminated chart holder comprising a I laminated barrel, saidbarrel consisting of an inher longitudinally split metal shell, toprovide a slot along the barrel, an outer metal shell of lesserarcuateextent than said inner shell and a layer of insulating material betweenthe shells;

. a rail formed on the inner shell adjacent and along therefore not becompleted unless the switch l0 is g the slot, a cooperating rail on theouter shell, a lamp housing slidable on the rails, an electric lightwithin the housing, means to connect the terminals of the light with therails, a battery. within the barrel, .and' means to connectthewterminals of the batterywith the inner and outer shells ofthebarrel. ii.
